COPYING-BOOK.

A SPECIFICATION forming part of Letters Patent No. 354,959, dated December 28, 1886.

Application filed February 12, 1886. Serial No. 191,740.

To all whom, it may concern.-

Be it known that 1, Loans E. WHITON, of West Stafford, in the county of Tolland and State of Connecticut, have invented a new and useful Improvement in Copying-Books; and I do hereby declare that the following is a full, elear,'and exact description of the same.

My invention relates to letterpress-copying books shown in an application filed by me in the United States Patent Ofiice on the 14th day of November, 1885, and numbered 182,798. The book described in said application is formed of thin leaves of paper adapted to letter-press copying and divided into sections by leaves of thicker paper having exposed mar ginal letters. The thick paperleaves are shown I as made with a part of the margin cut away in the usual manner of indexing by marginal letters. It was suggested in said application that the divisions could be separately supplied, in order that if any one division became exhausted another could beinserted. Ihave de vised means of supplying these divisions or signatures as an article of manufacture, adapted to be put together in a temporary binder in place of those exhausted, or to form an entire book, the divisions or signatures being adapted to be inserted in any position in the letterindex.

To this end my invention consists of a division or signature composed of leaves of ordinary letterpress-copying paper with a projecting or division cover of stouter paper on one or both sides of the division or signature, the leaf or one of the leaves having its margin extended beyond the edges of the letter-presscopying leaves and providedwith the letters of the alphabet arranged vertically on its exposed margin.

nila or any other suitable paper. The letter- (No model.)

I place theletters of the alphabet in their order. All the signatures being made in this way, they are all fitted for any position in the book, and when the signature is to be placed that part of the margin containing the letters of the alphabet is removed from the bottom up 6 to the letter which is to form the index-letter of the division. All of the remaining letters of the margin will be covered by the uncut portions of the margins of the preceding signatures or divisions. It will be understood that these divisions are formedwith the entire alphabet on the exposed margins, and are to be cut and fitted by the user, all being alike applicable to fit any place in the alphabet from A to Z.

I claim as my invention 1. A signature for letterpress copying books, composed of' ordinary letterpress-copying paper and a cover having anexposed margin with the letters of the alphabet placed 8o thereon in their order, substantially as described.

2. A signature for letterpress-copying books,composed of ordinary letterpress-copying paper and .a cover or divisional leaf of heavier paper having on one side an exposed margin with the letters of the alphabet placed thereon in their order and on the other side a margin exposed beyond the letterpress-copying paper with perforations for temporary 9o binder.

In testimony whereof I have signed my name to this specification in the presence of two sub-
